GEORGE WESTINGHOUSE, OF SCHENECIADY, NEIV YORK.

GRAIN-SEPARATOR.

Specification of Letters Patent No. 27,941, dated April 17, 1860.

To all whom it may concern:

Be it known that I, G. WESTINGHOUSE, of Schenectady, in the county ofSchenectady and State of New York, have invented a new and usefulImprovement in GrainSeparating Attachments for Threshing Machines; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which Figure 1, is a sidesectional view of my invention taken in the line 00, 00, Fig. 2. Fig. 2,a plan or top View of same.

Similar letters of reference indicate corresponding parts in the twofigures.

This invention consists in a novel arrangement of two carriers orscreens connected with the thresher substantially as hereinafter fullyshown and described, whereby the parts may be readily adjusted or set inproper working position and made to operate in the most efiicientmanner.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents a grain threshing machine which may be constructed in theusual or any proper manner.

B is the driving shaft of the thresher and a, a, are two cranks placedon said shaft in reverse positions with a pitman 0, attached to each,see Fig. 1.

D is a carrier or screen, constructed in the usual way; to wit, with aperforated bottom 6, and side strips 0, 0, the ends being open. Thiscarrier is suspended at its back to the discharge end of the thresher A,by rods cl, d, which are allowed to swing loosely from the frame of thethresher. The front end of carrier D, rests on friction rollers e, e, atthe back end of a carrier E, which is constructed similar to D.

The carrier E, has side bars f, 7, which extend back to the dischargeend of the thresher A, and are suspended therefrom by rods g, g, whichare just back of the rods 03, cl, which support the back end of carrierD. The front end of the carrier E, is supported by a rocking frame F,which is attached to the carrier E, by pins or bolts h, or both ends ofcarriers E, may be supported by rocking frames similar to F, dispensingwith the side bars f, f.

The front end of the carrier D, where it rests on the rollers e, e, isprovided with inclined ways i, one of which is shown clearly in Fig. 1.

In the outermost carrier E, a shaft G, is placed transversely. Thisshaft is provided with the teeth 7', which project from the shaft atright angles, and are quite close to and nearly parallel with thebottom. of carrier E. To one end of shaft Gr, an arm H is attached; theupper end of said arm being connected by a pivot 70, to a bar I, whichextends back and is attached to the frame of the thresher A.

The operation is as follows: The grain is fed to the thresher A, asusual and the straw is discharged therefrom on the innermost carrier D,the two carriers D, F, vibrating and moving in opposite directions inconsequence of the reverse position of the cranks a, a, relatively witheach other. The carrier D, as it vibrates has its outer end somewhatelevated, during its outward movements in consequence of the inclined.ways i, i, resting on the friction rollers e, c. This movement aids thedischarge of the straw from the carrier and favors the separation of thegrain from the straw. The straw passes from the carrier D to E, on whichit is subjected to an auxiliary shake motion by the action of the teethj, of shaft G, said shaft having a rock motion given it in consequenceof the movement of carrier E, and the connection of the arm H, of theshaft G, to the bar I, which is attached to the thresher. The straw inpassing along through the two carriers and being subjected to the shakemotions described, has the loose grain thoroughly separated from it, thegrain passing through the perforations in the bottoms of the carriers,and the straw discharged off from the end of carrier. E. Any properdegree of inclination can be given the carriers by adjusting the rods d,d, g, 9, higher or lower, holes being made through the upper parts ofsaid rods to permit of such adjustment, so as to regulate the movementof the straw through the carriers carrier E, whether the carriers aresuspended as clrcumstancesmay requlre for the perfect from the thresherframe or otherwlse, operseparation of the grain therefrom. ating asdescribed for the purpose set forth. 10

What I claim as new and desire to secure GEORGE WESTINGHOUSE. 5 byLetters Patent is Witnesses:

The combination of the carriers D and E, S. H. CAMPBELL, the carrier Dresting on the inner end of L. STEWART.
